The likeliest reason for the increase in height over the last fifty years in Druidia is an improved diet during infancy and adolescence. This is because good nutrition during early development is associated with healthy growth and development, and improved nutrition over the years may have allowed for greater growth and height in the population. The other options are not as likely to be associated with the increase in height. While an influx of genetically tall people could contribute to a height increase, it is unlikely that this would be the only reason, and there is no evidence to suggest that such an influx took place. Genetic changes over fifty years are unlikely to have a significant effect on height, as these changes typically occur over longer time periods. The country undergoing an industrial revolution or more people moving into cities and consuming more calories may lead to changes in average height, but the effects are more complex and uncertain.
